Generalization to more than two determining steps

It is easily conceivable that choosing three, four, or more determining steps and, ultimately, taking all the steps as determining can complicate the mode. We then obtain the general pseudo-steady state mode. 

The previous generalization leads to a generalization of the inverse rates law in the case of linear sequences and with the condition that all the steps involved have the same multiplying coefficient. Thus we have  

This generalized inverse rates law only leads to a form isfE if all the space functions are identical, as is the case in a homogeneous system. 

Similarly, a generalized law of the addition of characteristic times would be obtained.
